EFFECTS OF REACTOR RADIATION ON CERAMIC-BONDED SOLID-FILM LUBRICANTS

EFFECTS OF REACTOR RADIATION ON CERAMIC-BONDED SOLID-FILM LUBRICANTS

Two solid-film lubricant formulations (PbS MoS2 B2O3 and MoS2 graphite sodium silicate) have been exposed to reactor radiation and tested for wear life on a Hohman A-6 wear tester. Substrate material was Inconel X, rub shoes were of Rex AAA, load per shoe was 110 lb, and sliding speed was 128 ft/min...

Zusammenfassung:Two solid-film lubricant formulations (PbS MoS2 B2O3 and MoS2 graphite sodium silicate) have been exposed to reactor radiation and tested for wear life on a Hohman A-6 wear tester. Substrate material was Inconel X, rub shoes were of Rex AAA, load per shoe was 110 lb, and sliding speed was 128 ft/min. Several test temperatures up to 1200 F were employed. It was concluded that a gamma dose of 1.47 x 10 to the 11th power ergs/gm(C) and a neutron flux of 2.85 x 10 to the 16th power n/sq cm had no significant effect on the wear life of these films.
